You have helped me with many questions from the chemistry section. I still remember that one day i asked you about 25 questions from my chemistry Question bank and you went on answering without any single word of annoyance. You explained me everything with utmost dedication. The mysteries of chemistry becomes trivial to be understood with you.Thank you very much, for helping me with chemistry such that, now i am starting to get good grades in it. I shall always be obliged to your help :)
